Pollination of Blueberry (vaccinium Ashei) by Honey Bees (apis Mellifera) and Nectar-thieving Carpenter Bees (xylocopa Virginica)
In a 2000 field study in which mature plants, potted pollenizers, and 0-12800 honey bees were tented together, honey bees were shown to effectively pollinate rabbiteye blueberry, variety “Climax.” There was a consistent and significant increase in fruit-set and number of seeds as bee numbers increased within the range of 0-6400 bees. In conference, the authors will present results of a 2001 fie...

متن کاملPollination Services Provided by Bees in Pumpkin Fields Supplemented with Either Apis mellifera or Bombus impatiens or Not Supplemented
Pollinators provide an important service in many crops. Managed honey bees (Apis mellifera L.) are used to supplement pollination services provided by wild bees with the assumption that they will enhance pollination, fruit set and crop yield beyond the levels provided by the wild bees. Recent declines in managed honey bee populations have stimulated interest in finding alternative managed polli...
متن کاملPollinator Ecology and Management Managed Bumble Bees (Bombus impatiens) (Hymenoptera: Apidae) Caged With Blueberry Bushes at High Density Did Not Increase Fruit Set or Fruit Weight Compared to Open Pollination
Highbush blueberry (Vaccinium corymbosum L.) is an important crop grown throughout Florida. Currently, most blueberry growers use honey bees (Apis mellifera L.) to provide pollination services for highbush blueberries even though bumble bees (Bombus spp.) have been shown to be more efficient at pollinating blueberries on a per bee basis. In general, contribution of bumble bees to the pollinatio...
متن کاملHost Specificity in the Honeybee Parasitic Mite, Varroa spp. in Apis mellifera and Apis cerana
The ectoparasitic mite Varroa destructor is a major global threat to the Western honeybee Apis mellifera. This mite was originally a parasite of A. cerana in Asia but managed to spill over into colonies of A. mellifera which had been introduced to this continent for honey production. To date, only two almost clonal types of V. destructor from Korea and Japan have been detected in A. mellifera c...
